WAVE-MOTOR.

Specieation of Letters Patent.

Patented Mar. 14, 1916.

Application nea June 1s, 1915. semi No. 34,882.

citizen of the United States, residing at Council Bluffs, in the countyof Pottawattamie and State of Iowa, have Vinvented a new and usefulfave-Motor, of whichthe following is a specification.

The present invention appertains to wave motors, and is particularly animprovement over the wave motor disclosed in my' Patent No. 1,077,156,issued October 2S, 1913.

It is the object of the invention to provide Y a wave motor of novel andimproved con,

struction and operation, and adapted to be operated by the approachingand receding movements of the waves, and whereby motion is also obtainedby the varying heights of the waves.

Another object of the invention is the provision of a unique meansactuated by the waves, and adapted for operating the' pump or otherdriven mechanism for utilizing the power created called the multiple.

A further object of the invention is the provision of a wave motorhaving a pump associated orV combined therewith in a novel manner so asto be operated effectively for utilizing the dynamic energy derived fromthe movement of the waves.

It is also within the scope of the invention to provide a wave motorhaving the features above noted, which is also simple and inexpensive inconstruction, and which isv practical and efficient in operation.

Vith the foregoing and other objects in V-view which will appear as thedescription proceeds, the invention resides in the combination andarrangement of parts and'in the details of construction hereinafterdescribed and claimed, it being understood that changes in the preciseembodiment of the invention herein disclosed can be made within thescope of what is claimed without departing from the spirit of theinvention,

The invention is illustrated' inY its preferred embodiment in theaccompanying drawing, wherein the figure vis a vertical section of theimproved wave motor.

In carrying out the invention, there is provided a stand pipe or uprightcondult 1 having its upper end closed, as at 2, and having an outwardlyand upwardly curved portion or trap 3 at its lower end terminating in aliared mouth 4. T herstand pipe or `conduit 1 is erected at the shore ofthe body of water, and the portion 3 extends to the bottom or bed of thebody of water so as to lie below and receive the water therein, thestand pipe or conduit 1 projecting upwardly to a point above the highestcrest level of the waves.

A sea wall 5 is preferably' provided in front'of the stand pipe orconduit l, and in rear of the mouth 4 of the portion 3 for not onlyprotecting that part of the present apparatus in rear of the sea wall,but to also enhance the operation of the apparatus, by stopping thewaves above the mouth 4 of the portion 3, and causing the water to rushinto the lower portion 3 of the stand pipe or conduit 1 withconsiderable force or momentum.

The vertical `or up anddown .movement of the column of water within thestand pipe` or conduit 1 is utilized for operating an actuatingmechanism. This actuating mechanism comprises an upright Acylinder 6 soYdisposed atvone side of and parallel with Y the stand pipe or conduit 1,and having its lower end open,y while its upperl end is closed, as at 7.The lower end of the cylinder 6 is submerged in a tank or reservoir 8which is filled with water, and the water will therefore rise into thecylinder 6; The upper ends 2 and 7, respectively, of the stand pipe 1and cylinder 6 Vare connected bymeans of a. pipe 9 which establishescommunication between the upper ends of the stand pipe and cylinder, andthe upperends of the stand pipe and cylinder vare provided with therespective safety or air escape valves 10 and 11.

A piston 12 works within the cylinder 6 and is disposed slightly belowthe level of the water within the cylinder, whereby the piston will becarried upwardly and down-V wardlywith the column of water within thecylinder. The piston 12 is attached to a vertical reciprocatory pistonrod 13 which projects upwardly and downwardly from the piston and slidesthrough theupper endv ofthe cylinder 6 and the -bottom of the tank Y 8,respectively.

The reciprocatlon of the rod 13 is utilized for o-perating avwater pump14, which embodies an upright cylinder 15 disposed below the tanlr 8concentric or in alinementV with the cylinder 6, and a piston 16 whichoperates within the cylinder 15 is attached tothe lower end of thepiston rod 13. Thus,

than the lower cylinder 15; and' piston'16,

whereby the pump will be properly operated in the manner of a hydraulicram.;

The upper and lower ends of the pump cylinder 15 are provided with theinlet pipes 17 and 1S, respectively, which are provided cylinder, toIrender the' operation of the` pump. easy. The upper and lower ends ofthe p ump cylinder are also provided with outlet pipes 22 and 23 havingthe check valves 211 and 25 which allow the water to pass through theoutlets, and which prevent the return of the waterfbaclr into the'pumpcylinder. The outlet pipes 22 andr23rare connected with a pipe 26 whichextends upwardly to a tanlror Vother device .for receiving or utilizingthe water pumpedupwardly by the` pump. Y Y.

The cylinder'6, tank 8, andcylinder 15 arey preferably, although notnecessarily, mounted within aholeldug in the ground.

Iiroperation, when theV device isstarted, the first wave in passing overthe mouthf of the conduit or standpipe 1 will cause thel column of waterwith the stand pipe to rise, thus forcing the air from the upperend ofthe stand pipe into the` cylinder 6, the valve llbeingy opened topermitenough air to escape, so that onlya normal pressure of air remains,1inorderv that-when the wave recedes,.the column ofl water within the standpipe 1 will fall by gravity. This will` suck` the air from the cylinder6 thereby tending to create al vacuumwhich will result inthe atmosphericpressure at thebase of the .cylinder 6forcingv the column ofwater toascend` within thesame. high inthe stand, pipeV it is low in the cyl-linder 6, and vice versa,vthereby resembling a see-saw. By the waveaction over the mouth of the stand pipe or conduit 1, ythe great weightof the water is alternated/between the stand pipe 1 and cylinder 6, asabove indicated. The upward stroke of the water'witliinf the cylinder 6is caused by atmospheric pressure, the falling ofthe column of-water in`the stand pipe 1, and the tendency to create av vacuum between thestand, pipe andv cylinder, and the 'downwardv stroke of the column ofwater within the cylinder iscaused by the pressure of the air between`the stand. pipe and; cylinder. The-column of waterfwithin thecylinder 6whenrrisingawillcarry the piston 121 upA When the water is' wardly'therewith, and this will" move the piston 16 of the pump upwardly toeject the water from the Mupper end of the pump cylinder 15, and toallow the water to flow intoV the lower portion of the pump cylinder.Vhen the next wave passes over and enters the `trap portion 8 of the`standpipeI 1, it will again raise the column of water within the standpipe, and will force the air through the pipe 9 into the cylinder 6- forforcing, the column of water downwardly within the cylinder 6, and tothereby move* the piston 12 downwardlywliich, will also force the pumppiston; 16 Y downwardly.`

rlhe pump piston 16 being` moved downsY wardly, will eject thewaterfrointhe lower.

end of` the pump cylinder, while the water will enter the upper end. ofthe pump cyl-KY inder. The pump is double acting, sozas to operate uponboth the upward and down ward strokesof .thepiston rod13, andthewaterwill be elevated or raised throughl the pipe Q6 toa ,tank or otherdevice utilizing. vIt will. thereforevbe seen that theY verticalmovement of the coluninuoff the Y water.

water within' tlicvstandpipe is transmitted-Ql pneumatically to thecolumn of w-ater with-'- in thev cylinder 6, for" reciprocating thepower piston 12, and the columnsof` watera' within. the stand pipe4 andf cylinder iny counter balancing one another, .renderthe' operation ofthe device easy. The power4` piston 12 being submerged, within.,v thecolumn. of water within;thecylinderiwill be'carried upwardly anddownwardly prop,-v

erly with thesaid column of water, to oper-f-l ate the pump piston 16,andy the pump,Y cyl'- inder 15 lying below the level. ofl the-waves# orbody of water will allow theI water. to

flow into the` pump cylinder by gravity which. enables the pump to be.operated-with, theA least possible effort,1 and to thereby;

increase the efficiency ofthe motor.

A number ofcylinders Gmay be connected to the upper end ofthestand/pipe. 1 byL means of av plurality. of pipes: 9, if-1ity ist:ydesired to operate a numberof-pumps. A: slide-valve 27` maybefemployedsfor closing:i the pipeV 9 for. stopping all mechanical.-
